Learning to detect dysarthria from raw speech

open access: yes, 2019
Speech classifiers of paralinguistic traits traditionally learn from diverse hand-crafted low-level features, by selecting the relevant information for the task at hand. We explore an alternative to this selection, by learning jointly the classifier, and

MusicSwarm: Biologically Inspired Intelligence for Music Composition

open access: yesAdvanced Intelligent Systems, EarlyView.
Biologically inspired swarms of frozen foundation models self‐organize to compose complex music without fine‐tuning. By coordinating through stigmergic signals, decentralized agents dynamically evolve specialized roles and adapt to solve complex tasks.

Gate‐Align‐SED: Semi‐Supervised Sound Event Detection via Adaptive Feature Gating and Cross‐Task Alignment in Situation Awareness

open access: yesAdvanced Intelligent Systems, EarlyView.
Overview of the proposed Gate‐Align‐SED, including two stages of training: (1) Mean‐Teacher SSL Training; and (2) Enhancer Model Training. In complex real‐world environments such as disaster monitoring, effective sound event detection (SED) is often hindered by the presence of noise and limited labeled data.

A Multimedia Application: Spatial Perceptual Entropy of Multichannel Audio Signals

open access: yesEURASIP Journal on Wireless Communications and Networking, 2010
Usually multimedia data have to be compressed before transmitting, and higher compression rate, or equivalently lower bitrate, relieves the load of communication channels but impacts negatively the quality.

Integration of Road Data Collected Using LSB Audio Steganography

open access: yesTechnologies
Modern traffic-monitoring systems increasingly rely on supplemental analytical data to complement video recordings, yet such data are rarely integrated into video containers without altering the original footage.

The effect of dynamic range compression on the psychoacoustic quality and loudness of commercial music [PDF]

open access: yes, 2010
It is common practice for music productions to be mastered with the aim of increasing the perceived loudness for the listener, allowing one record to stand out from another by delivering an immediate impact and intensity.

Group-theoretic structure of linear phase multirate filter banks

open access: yes, 2013
Unique lifting factorization results for group lifting structures are used to characterize the group-theoretic structure of two-channel linear phase FIR perfect reconstruction filter bank groups. For D-invariant, order-increasing group lifting structures,

Innovative Artificial Intelligence‐Assisted Systems for Social Science Research: Architecture Design and Applied Practice

open access: yesAI &Innovation, EarlyView.
ABSTRACT The rapid advancement of large language model (LLM) technology is profoundly transforming the practice of social science research. Scholarly discussions on Artificial Intelligence (AI)'s role in social science research can be organised into three levels: AI as a research tool, AI as a methodological infrastructure and AI as a quasi‐cognitive ...

Proprietary software tools as learning aids [PDF]

open access: yes, 2007
Proprietary software tools, though not designed for educational use, have considerable educational potential. This paper describes, as case studies, the use of proprietary graphics- and audio-editing tools in two distance-taught courses produced by the ...
